 At least there is some hope:

 # Roadmap

 The plan is the following:

 ### Reached
 1. Complete C implementation of the decoder,
 2. Provide a usable API,
 3. Port to most platforms,
 4. Make it fast on desktop, by writing asm for AVX2 chips.
 5. Make it fast on mobile, by writing asm for ARMv8 chips,
 6. Make it fast on older desktop, by writing asm for SSSE3+ chips,
 7. Make high bit-depth fast on mobile, by writing asm for ARMv8 chips.

 ### On-going
 8. Make it fast on older mobile, by writing asm for ARMv7 chips,
 9. Make high bit-depth fast on older mobile, by writing asm for ARMv7
 chips,
 10. Improve C code base with [various
 tweaks](https://code.videolan.org/videolan/dav1d/wikis/task-list),
 11. Accelerate for less common architectures, like PPC, SSE2 or AVX-512.

 ### After
 12. Make high bit-depth fast on desktop, by writing asm for AVX2 chips,
 13. Make high bit-depth fast on older desktop, by writing asm for SSSE3+
 chips,
 14. Use more GPU, when possible.

 - We do, but we don't have either the time or the knowledge. Therefore,
 patches and contributions welcome.
